AR Number Place Solver

[How to use]

Once launched, it is an easy operation just to point the camera to the problem of number place.

If you want to get only once and stop the screen, use "Single". Even if you tap the image area, it is also the operation of "Single".

"Continuous" executes image input-answer display repeatedly. At first it is this state.



[About screen display]

When the answering process is completed, the original number (green) and answer (pink) are displayed on the screen. If the original numbers are recognized correctly, the answer will also be correct.

Even if the recognition of the original number is wrong, if the process goes to the end, the (incorrect) answer will be displayed. In this case, adjust the camera position and lighting conditions until the original numbers are correctly recognized.



This application corresponds to the general rule of number place (Sudoku).

"Info." shows the version number and privacy policy. The application closes by "Exit".



[To make it recognize well]

The trick is to reduce the curvature of the paper from the front as much as possible and shoot in a bright environment with few shadows. Also, please hold the camera without shaking.



[Algorithm]
